Abstract
The present article describes development and testing of a new measurement method that enables nondestructive and in situ monitoring of a vacuum carburizing process. The principle of the method is based on monitoring the carbon diffusion during vacuum carburizing by the in-situ measurement of electrical resistance changes in the carburizing sample. Using this method the electrical resistance changes during vacuum carburizing of pure iron were acquired and analyzed. The experiments were performed in a laboratory vacuum furnace under a low pressure acetylene atmosphere (5 mbar) at a temperature of 950°C. The results of monitoring the kinetics of carburized zones obtained by the novel measurement method were compared with kinetics obtained by metallographic analysis of carburized samples.
